Airborne-laser-scanning-derived auxiliary information discriminating between broadleaf and conifer trees improves the accuracy of models for predicti…
2020
Managing forests for ecosystem services and biodiversity requires accurate and spatially explicit forest inventory data. A major objective of forest management inventories is to estimate the standing timber volume for certain forest areas. In order to improve the efficiency of an inventory, field based sample-plots can be statistically combined with remote sensing data. Such models usually incorporate auxiliary variables derived from canopy height models. The inclusion of forest type variables, which quantify broadleaf and conifer volume proportions, has been shown to further improve model performance. Currently, the most common way of quantifying broadleaf and conifer forest types is by ca…
Heritability of Lifetime Income
2013
Using 15 years of data on Finnish twins, we find that 24% (54%) of the variance of women’s (men’s) lifetime income is due to genetic factors and that the contribution of the shared environment is negligible. We link these figures to policy by showing that controlling for education reduces the variance share of genetics by 5-8 percentage points; by demonstrating that income uncertainty has a genetic component half the size of its variance share in lifetime income; and by exploring how the genetic heritability of lifetime income is related to the macroeconomic environment, as measured by GDP growth and the Gini-coefficient of income inequality.
Follow-Up Data Improve the Estimation of the Prevalence of Heavy Alcohol Consumption.
2018
Aims. We aim to adjust for potential non-participation bias in the prevalence of heavy alcohol consumption. Methods. Population survey data from Finnish health examination surveys conducted in 1987–2007 were linked to the administrative registers for mortality and morbidity follow-up until end of 2014. Utilising these data, available for both participants and non-participants, we model the association between heavy alcohol consumption and alcohol-related disease diagnoses. Results. Our results show that the estimated prevalence of heavy alcohol consumption is on average of 1.5 times higher for men and 1.8 times higher for women than what was obtained from participants only (complete case an…
Relative and absolute socioeconomic inequality in smoking: time trends in Germany from 1995 to 2013
2020
Abstract Purpose This study aimed to investigate time trends in relative and absolute socioeconomic inequality in smoking prevalence in Germany using several indicators for socioeconomic position. Methods We conducted a repeated cross-sectional study using representative samples of the German population aged between 25 and 64 years in 1995, 1999, 2005, 2009, and 2013 (n = 857,264). Socioeconomic position was measured by indicators for income, education, and occupation. Relative and absolute socioeconomic inequalities were estimated with the regression-based relative index of inequality and the slope index of inequality, respectively. Trends in inequalities were estimated with interaction te…
The EUROCARE-5 study on cancer survival in Europe 1999-2007: Database, quality checks and statistical analysis methods
2015
Abstract Background Since 25 years the EUROCARE study monitors the survival of cancer patients in Europe through centralised collection, quality check and statistical analysis of population-based cancer registries (CRs) data. The European population covered by the study increased remarkably in the latest round. The study design and statistical methods were also changed to improve timeliness and comparability of survival estimates. To interpret the EUROCARE-5 results on adult cancer patients better here we assess the impact of these changes on data quality and on survival comparisons. Methods In EUROCARE-5 the survival differences by area were studied applying the complete cohort approach to…
Fiscal adjustments, labour market flexibility and unemployment
2014
Using a panel of 17 countries for 1978-2009, we find that tax-driven consolidations increase unemployment by 0.25 percentage points. Labour market flexibility mitigates this: a one-point rise in the flexibility index reduces youth (long-term) unemployment by 0.6-0.7 (1.8-2.2) percentage points.
Does the internet increase the job finding rate? Evidence from a period of expansion in internet use
2021
Abstract We examine the impact of household access to the internet on job finding rates in Germany during a period (2006–2009) in which the share of households with a broadband connection increased by 31 percentage points, and job-seekers increased their use of the internet as a search tool. During this period, household access to broadband internet was almost completely dependent on the availability of a particular technology (DSL). We therefore exploit the variation in DSL availability across municipalities as an instrument for household access to the internet. OLS estimates which control for differences in individual and local area characteristics suggest a job finding advantage of about…
Vertical FDI Revisited
2003
This study explores how relative skilled-wage premia affect FDI. Contrary to previous studies based on factor endowment differences, we find strong support for vertical FDI, in the sense that more FDI is conducted in countries where unskilled labor is relatively cheap. In addition, we find that relative skill-premia also affect FDI activities that have previously been associated with horizontal FDI, i.e. local affiliate sales. Consequently, the potential effects of changes in the relative wage costs on international production reallocation within MNEs are large. In fact, if not for the 8% rise in the US skilled wage premium relative to the average host country between 1986- 1994, annual US …
Matching inefficiencies, regional disparities and unemployment
2009
. In this paper we apply a stochastic frontier approach to examine how matching inefficiencies and regional disparities in structural factors contribute to regional and aggregate unemployment. Our results suggest that there would be a substantial decline in aggregate unemployment if (i) all local labour offices operated with full efficiency or (ii) they shared the same structure of job seekers and vacant jobs as the most favourable office. In the former case an increase in hirings would lower the average unemployment rate by 2.4 percentage points. In the latter case the decrease would be 1.4 percentage points. Further, we find that fixed effects are positively correlated with both a more f…
Employment Effects of Skills Around the World: Evidence from PIAAC
2017
Making use of an international survey that directly assesses participants’ cognitive skills, I study the effect of skills on workers’ employment in 32 countries. On average, a one-standard-deviation increase in numeracy skills is associated with a 7.6 percentage points increase in the probability of being employed. Controlling for years spent in education, the employment effect of numeracy skills falls to 4.8 percentage points. Numeracy skills account for 30 percent of the 2.7 percentage points employment effect that is associated with years of education. There is considerable heterogeneity across both subgroups and countries.
